停止免费订单的 WooCommerce 管理员电子邮件通知

问题描述

如果订单值为 $0.00，我想停止 woocommerce 电子邮件通知

我使用了这个代码：

function restrict_admin_new_order_mail( $recipient,$order ) {
    if( $order->get_total() === '0.00' ) {
        return;
    } else {
        return $recipient;
    }
}
add_filter('woocommerce_email_recipient_new_order','restrict_admin_new_order_mail',1,2);

代码正常运行，但我遇到了这个致命错误，Woocommerce 设置中的所有电子邮件选项都消失了（请参见附加的屏幕截图）。

解决方法

看看。

bool value1 = false;
bool value2 = false;
bool value3 = true;
bool value4 = false;

您可以定位不同的电子邮件woocommerce_email_recipient_customer_processing_order

为避免此错误，您需要在函数的开头添加此简单行：

shipment_id

我也重新审视了你的代码……试试这个：

if ( ! is_a( $order,'WC_Order' ) ) return $recipient;

代码位于活动子主题（或活动主题）的functions.php 文件中。现在应该可以使用了。
